Chapter 5.3 Solving Trigonometric Equations
Objectives • Verify x-values that are solutions of an equation
Ex: 1 Plug And Chug!Verifying an equation at a given x-value • Given x = π/8, verify that the x-value is the solution of the equation:
Ex: 1 Plug And Chug!Verifying an equation at a given x-value
Ex. 2A: Finding the solutions to an equation • Solve for x over the range of 0 < x < 2π • Get the trig value by itself, or at least as a power of itself
Ex. 2A: Finding the solutions to an equation • Check the unit circle for viable x values
Ex. 2B: Finding the solutions to an equation • Solve for x over the range of 0 < x < 2π • Notice there are two factors, if either factor is 0, then the equation will equal zero • Therefore, you need to solve for each equation
Ex. 2C: Finding the solutions to an equation • Solve for x over the range of 0 < x < 2π • Notice there are two trig functions, so pay close attention so you can get them to equal the same trig function
Ex. 2C: Finding the solutions to an equation • Now you can get all the trig functions onto one side.
Ex. 2C: Finding the solutions to an equation • Now you can factor!
